Title: Polarized electromagnet
Inventor: KAWASAKI KENJI
IPC: H01F7/08
Filed: 1982-03-12
Abstract: PURPOSE:To regulate the attracting force of an armature delicately in a wide range by a construction wherein a non-magnetic material is added to at least one of the magnetic poles of a permanent magnet forming a magnetic path. CONSTITUTION:A permanent magnet 2 is arranged so that its upper yoke side 1 is negatively polarized and a non-magnetic material 3 is interlockingly added to the other pole S through which a lower yoke 4 is arranged. A central piece 5a is provided with a U-shaped armature 5, so that side pieces 5b, 5c can be arranged in an air gap between both the ends of the lower yoke 4 and side plates 1b, 1c. The armature 5 is driven to the left and right according to the strength of the magnetic flux of the air gap at both the ends of side pieces 5b, 5c depending on the direction of the current flowing through a coil 6. At this time, because the magnetic flux in the magnetic path is weakened by the non-magnetic material 3, the attracting force of the armature can readily be regulated by obtaining the same effect as if the permanent magnet 2 were demagnetized.

Title: Method and device for driving gate turn-off thyrister
Inventor: NAKAGAWA AKIO
IPC: H01L29/74
Filed: 1987-02-26
Abstract: PURPOSE:To decrease a tail current value and a tail period at the time of turning off by impressing an off-pulse to a first gate electrode when a gate turn-off thyrister is driven to turn-off, and impressing the off-pulse to a second gate electrode when the forward voltage drop of an element exceeds a prescribed value. CONSTITUTION:A set value due to a voltage setting device 8 is E0. As a time t2 from the on-pulse impression of the second gate electrode up to an off-pulse impression, an inter-anode/chathode voltage VA(t2) detected by a voltage detecting device 4 when the off-pulse is impressed to the second gate electrode is converted to a digital signal by the A/D converter of an arithmetic processing circuit 7. When E0>VA(t2), a time  t is made variable in accordance with the voltage VA(t2), the timing of the off-pulse impressed to a first gate electrode 17 is impressed to a second gate electrode 18 and  t only is proceeded. On the other hand, at the time of E0=VA(t2), a trigger is continued at a fixed timing. Thus, a tail current initial value is decreased and a tail period is decreased.
